Chao Sun updated HIVE-14340: ---------------------------- Attachment: HIVE-14340.1.patch Attaching new patch. This changes {{hive.query.hooks}} to {{hive.query.lifetime.hooks}}. Also, now the hook activates at 4 places: # before query compilation # after query compilation # before query execution # after query execution > Add a new hook triggers before query compilation and after query execution > -------------------------------------------------------------------------- > > Key: HIVE-14340 > URL: https://issues.apache.org/jira/browse/HIVE-14340 > Project: Hive > Issue Type: Improvement > Components: Query Processor > Affects Versions: 2.2.0 > Reporter: Chao Sun > Assignee: Chao Sun > Attachments: HIVE-14340.0.patch, HIVE-14340.1.patch > > > In some cases we may need to have a hook that activates before a query > compilation and after its execution. For instance, dynamically generate a UDF > specifically for the running query and clean up the resource after the query > is done. The current hooks only covers pre & post semantic analysis, pre & > post query execution, which doesn't fit the requirement. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
